2. I
rms
Amps for approximately ΔT of 40°C. DC current for an approximate ΔT of 40°C without
core loss. Derating is necessary for AC currents. It is recommended that the temperature of the part
not exceed 125°C under worst case operating conditions verified in the end application.
3. I
sat
Amps Peak for approximately 30% rolloff @ 20°C.
4. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at 200kHz
necessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise.
See Core Loss Graph.
5. Part number definition - HC1-xxx-R:
HC1 = Product code and size
-xxx = Inductance value
R = Decimal point (if no “R” is present, last character equals number of zeros )
-R Suffix = RoHS compliant
